This document is a summary of the report to Congress intended to provide decision makers with an objective appraisal of the physical conditions, operational performance, and financing mechanisms of highways, bridges, and transit systems based both on the current state of these systems and the projected future state of these systems under a set of alternative future investment scenarios.

The Highway Statistics Series consists of annual reports containing analyzed statistical data on motor fuel; motor vehicles; driver licensing; highway-user taxation; State and local government highway finance; highway mileage, and Federal aid for highways. This data is presented in tabular format as well as selected charts and has been published each year since 1945.

This paper focuses on the factors causing total fuel use to rise, including car ownership and use and new vehicle characteristics, and on the components of that rise might be changing towards restraint of fuel use.

This report presents the hypothesis that the United States has reach a critical juncture in terms of national mobility trends and underlying socio-demographic conditions and travel behavior that will result in more moderate rates of annual VMT growth in the future. It explores the major factors that influence travel behavior and forecasts future VMT built on the data and information presented in the body of the report.

This report, published in September 2008, provides data on the fuel economy and technology characteristics of new light-duty vehicles (cars, minivans, sport utility vehicles, and pickup trucks) for model years 1975 through 2008. This report confirms that average fuel economy has improved each year beginning in 2005, is now 1.5 miles per gallon higher than in 2004, and is the highest since 1993. This reverses a long term trend of slightly declining fuel economy since its 1987 peak.

National Transportation Statistics presents statistics on the U.S. transportation system, including its physical components, safety record, economic performance, the human and natural environment, and national security. Chapter 4 provides data related to energy consumption, fuel efficiency, and air pollution. This is a large online document comprising more than 260 data tables plus data source and accuracy statements, glossary and a list of acronyms. This Internet edition of the National Transportation Statistics is updated quarterly.

This report uses the latest federal data to identify VMT patterns across the country, and includes roadway, vehicle, state, and metropolitan comparisons. It is intended to provide policymakers with a better understanding of U.S. driving behavior as it pertains to frequently used roadways , typical vehicles used, and common travel patterns.

The Transportation Energy Data Book is a statistical compendium published annually by the Center for Transportation Analysis (CTA). Designed for use as a desk-top reference, the data book represents an assembly and display of statistics and information that characterize transportation activity, and presents data on other factors that influence transportation energy use.
